Tkinter window not closing after closed file dialog

I would like to close the File Open dialog after selecting a file. Currently with my code, I can select a file but the File Open dialog remains open until I click the 'X'. How can I close this window after I have selected a file.

Here is my code:

import sys
from tkinter import *
from tkinter.filedialog import askopenfilename   

fname = "unassigned"

def openFile():
    global fname
    fname = askopenfilename()

if __name__ == '__main__':

    b = Button(text='File Open', command = openFile).pack(fill=X)
    mainloop()

    print (fname)

The file dialog is closing just fine. I think what you are trying to say is that the Tkinter window you created to hold the button is not closing after you select a file from the dialog. To have it do this, you will need to restructure your program a bit.

First, you need to explicitly create a Tk window to hold the button:

root = Tk()

You should then list this window as the button's parent:

Button(root, text='File Open', command = openFile).pack(fill=X)
#      ^^^^

Finally, you should call the destroy method of the root window at the end of openFile:

root.destroy()

This will cause the window to close and the Tkinter mainloop to exit.

In all, your script will look like this:

import sys
from tkinter import *
from tkinter.filedialog import askopenfilename   

fname = "unassigned"

def openFile():
    global fname
    fname = askopenfilename()
    root.destroy()

if __name__ == '__main__':

    root = Tk()
    Button(root, text='File Open', command = openFile).pack(fill=X)
    mainloop()

    print (fname)
